Noun. Nothing, an Americanism for zero. Mainly used be people trying to poorly imitate an American accent for piss poor comedic effect.

Usage Example:

Joe: “Sorry buddy, I’ve got zilch, yeehaw!”
Me: “Why do you talk like a cowboy when you’re from Barnsley?”

Dude, you better not be trying some XSS bullshit, script kiddie!

How can you screw this up, seriously, just leave it be!

Just type in your example, it’s not rocket science!
